Application filed November 7, 1925. sem No. 07,626.

This invention relates to decorative trimming or ornamentation for transparent articles such as mirrors, windows, plaques, hou'seholdware, and the like, and to a process for producing same.

An object of the invention is the provision of a simple and inexpensive method for producing ornamentation of the character and on articles such as described and which shall require a minimum degree of skill in the carrying out thereof.

Another object is the provision of a trlmming of the character described which shall give highly artistic effects and yet comprise simple elements, easy to apply and comparatively inexpensive and highly ractical for use in decorating articles of t e character described.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accom anyingdrawing, in which is shown one o the various possible illustrative embodiments of this invention,

Fig. 1 is a front view of a mirror having a trimming embodying the invention applied to one side thereof; and

Figs. 2, 3, 4 and 5 are enlarged cross-sectional views each corresponding to a cut taken on line 22 in Fig. 1 at progressive steps of the improved process.

Referring in detail to the drawing, 10 denotes a plate of glass or other transparent or translucent material having an ornamental triming 11 formed on the rear side thereof by the process embodying the invention. Said trimming 11 is seen to comprise grooves 13 enclosing a ortion .12 of the rear surface 12- of t e glass 10, rosettes 14, and other ornamental elements such as 15, 16, 17, 18 and 19 arranged to form a desired artistic design within said portion 12 as shown in Fig. 1. The grooves, rosettes, and ornamental elements are depressed in the rear surface 12 of the glass by molding, cutting, etching, or in .any

other suitable manner well known in the art.

After providing the glass 10 with the detion 16" sired design depressed in the rear surface 12 thereof, each surface portion formin the rosettes 14 and the other ornamenta elements 15, 16, 17, 18 and 19 is finished for giving adesired contrasting effect. To this end, as shown in Figs. 1 and 2, the petal portions 14 of the rosette 14, leaf portion 16" of the element 16, and element 18 may be ground rough to have a mat surface, while the center portion 14 and stem porof'the rosette 14 and element 16, respectively, and elements 15 and 19 may be finished to have a smooth, highly polished surface. A variety of suitable o aque coatings are then applied to the fihished depressed surfaces of the design, for example pigment colors 21 and 22 are applied to the rosettes, petals 14 and elements 15 respectively. After said colors have been thoroughly dried, silver films 23 and 24 are formed over the rosette centers 14 and element 16, respectively, the elements 18 and 19 being coated similarly to said rosette petals and centers, respectively, as shown in Fig. 3. The rough-cut, mat surfaces of the design not only serve to better retain the adhering coating thereto than do the smoothly polished surfaces, but also are effective to give contrasting appearance of the finished design as viewed from the front side 10 of the glass 10. Thus, a pigment color as seen behind a rough-cut, mat surface appears to be stippled or pebbled, whereas on smooth polished surfaces said color appears glossy, while a silver film on the mat surfaces when viewed from the front of the glass has the appearance of a frosting or shimmering effect whereas on smoothly polished surfaces said film is highly reflecting and image forming.

A protective layer 25 of paint, varnish or laquer is then applied over the said opaque coating as shown in Fig. 4.

In the foregoing step of the process no particular care need be exercised in preventing the coating or protective layer from over-running the rear surface portion 12" so that the work can be carried on with a minimum degree of skill in manipulation. Next with the aid of a mulett or other suitable scraping and polishing apparatus, the surplus portions of the coatings and protective layers on the surface portion 12 are removed to leave onl the depressed surface covered, thus comp eting the trimming 11 (see Fig. 5).

If desired, the undepressed rear surface portion 12 and the rear surface portion 12 adjacent the edge of the glass 10 may be painted with a contrasting opaque colored background or silvered to form a mirror in the well understood manner.

It will thus be seen that there is provided a device in which the several objects 01E this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

1. The process of ornamenting transparent material consisting in forming a depressed design on the rear surface of the material, applying an opaque coating to com pletely cover the design, drying said coating, superimposing a protective layer over said dried coating and polishing said rear surface to remove said coating and layer from the undepressed portions thereof.

2. A step in a process of decorating or ornamenting designs depressed in one surface of a sheetof transparent material and having an opaque coating covering said design, the application of a protective layer over said coating prior to removing said coating on the undepressed portion of said surface. 4

In testimony whereof we afiix our signatures.
